Mini-LED display found in Apple 12.9 inch iPad Pro, which glows halo effect with high contrast.

Apple launched its ultra-modern iPad Pro earlier in April this year. Apple’s newly introduced iPad Pro is known as the most expensive and largest tablet. This 2021 iPad edition is designed with 12.9 inches and has a modernized mini LED backlight. Recently according to some reports, there has an issue reported by the users about the blooming problem. The display included in this iPad is a unique one, but similar to this category, a local zone lighting has been utilized in the monitors and televisions for a definite time, and the same effect was discovered in the screens. However, those who are worried about this feature should know that they can fix the issue.

According to the reports of MacRumours, regardless of the claims said by the tech giant, some of the users of the latest iPad Pro have discovered blooming, whereas some of the other users have not. The latest iPad Pro is made with 2,500 local dimming zones, which is due to LED display technology. The local dimming zones help to dim the LED screen in certain areas to provide truer blacks. And at the same time, it also protects the parts of the brighter screen. This technology helps the contrast ratio to increase at a high level while highlighting the HDR content.

As mentioned earlier, televisions and computer screens utilize similar display content. In earlier days, the bulky cathode-ray tubes (CRT) were known as the dominant type, which relied on electrons shot at a phosphor-coated screen to brighten the pixels. Over the last few decades, liquid crystal displays have become the popular option that alters the method of CRT and blocks the light supplied from behind the panel. Due to this, backlighting becomes necessary, and this is the place where recent changes have been made. The displays that are based on organic light-emitting diodes (OLED) directly generate light for each pixel and are well-liked among smaller devices. However, they drive the cost higher if used in larger displays.

Features of iPad Pro

The newer 12.9-inch model iPad Pro is designed with a high-quality XDR display with an excellent one-million-to-one contrast ratio and also 1600 units of peak brightness. This model can display high-dynamic-range content with deep blacks and brilliant whites. However, it is not considered an ideal display, and some people also discovered blooming a small amount. The blooming issue had some fine details, which includes high contrast areas like white text displayed on black background. According to the rumors, Apple is working on micro-LED displays, which will solve this problem. Currently, the technology lights the pixel directly the same as OLED while ignoring the burn-in issues that often decrease the life of the latter. In the meantime, bias lighting appears to be the solution to minimize this effect, which is also explained in a ‘Popular Science’ article about the blooming concept seen in televisions.

iPad Pro Bias Lighting and Halo Effect: Problem and Solution

The reason behind the appearance of the blooming text is the difference in the number of the LCD pixels and backlighting zones. This model utilizes mini LED backlighting, known as the array of 10,000 points of light, an astonishing number for a screen with a 12.9-inch size. Some televisions with larger screens exceed the number but manage to cover an area that is 15 to 20 times larger. This indicates the backlight resolution, which is still lower. This also implies that the appeared halo effect on the iPad Pro is relatively minor in comparison to what we have seen on televisions. Due to the common activity of high-contrast text on a tablet, it can increase more frequently.

The solution of bias lighting requires lighting the area behind the screen. During the time this is performed with LED strips placed behind the screen, fixed lighting for televisions, it is not considered practical to attach LEDs to the back of the 12.9-inch model. It is easy to avoid bias lighting by facing the window or nay brighter part of your room. According to ‘Popular Science,’ this affects the way humans receive contrast, which means without removing the glow issue, it changes the way a person sees it and will ease the concerns. If you are still bothered by the blooming issue, prefer its predecessor iPad Pro model, as it is still in demand and utilizes traditional backlighting.
